Abstract
Parenterally administrable oil-in-water emulsions formed from nutritive oils, such as soybean and sunflower oils, are improved first by treating the nutritive oil with silicic acid to remove undesirable components such as peroxides, pigments, thermal and oxidative decomposition products, certain unsaponifiable matter such as sterols, and polymers. Purification is effected by treating the oil with silicic acid or silica gel either directly, or as a solution thereof in a suitable solvent, such as hexane. Autoxidation of the purified oil is prevented by adding to the purified oil a tocopherol antioxidant, .gamma.-tocopherol being preferred. There is also added a metal scavenging agent such as ascorbyl palmitate.
